In MLIR we have out-of-tree [examples](https://github.com/llvm/llvm-project/tree/main/mlir/examples/standalone) that are actually built in CI to in order exactly to exercise such patches.

Couldn't you run the pipeline locally and figure out the missing file issue earlier? Why do you need to trial and error for the llvm-project part?
